>>712773227they mostly are, but honestly go back and look and any of the first look videos on him and try to differentiate t3/4/5 at a glance, never mind t1/2, they genuinely change very little and it makes it kind of hard to tell what tier they are (t5 bottom is the exception but it's really not enough)
i mean, think of any other t5 in primary, would you ever have a hard time telling what tier of tack you had out on the field? t4/5 should really look drastically different to anything below it and to each other, it does on every other tower in the game
